| RTE | Runtime Environment |
| WdgM | Watchdog Manager |
| Alive Counter | An independent data resource in the Watchdog Manager in context of a Checkpoint to track and handle its amount of Alive Indications. |
| Alive Indication | An indication provided by a Checkpoint of a Supervised Entity to signal its aliveness to the Watchdog Manager. |
| Alive Supervision | Kind of supervision that checks if a Supervised Entity executed sufficiently often and not too often (including tolerances). |
| Checkpoint | A point in the control flow of a Supervised Entity where the activity is reported to the Watchdog Manager. |
| Deadline Supervision | Kind of supervision that checks if the execution time between two Checkpoints are lower than a given upper execution time limit. |
| Deadline Start Checkpoint | A Checkpoint for which Deadline Supervision is configured and which is a starting point for a particular Deadline Supervision. |
| Deadline End Checkpoint | A Checkpoint for which Deadline Supervision is configured and which is an ending point for a particular Deadline Supervision. It is possible that a Checkpoint is both a Deadline Start Checkpoint and Deadline End Checkpoint – if Deadline Supervision is chained. |
| Expired Supervision Cycle | A Supervision Cycle where the Alive Supervision has failed its two escalation steps (Alive Counter fails the expected amount of Alive Indications (including tolerances) more often than the allowed amount of failed reference cycles). |
| Failed Supervision Reference Cycle | A Supervision Reference Cycle that ends with a detected deviation (including tolerances) between the Alive Counter and the expected amount of Alive Indications. |
| Global Supervision Status | Status that summarizes the Local Supervision Status of all Supervised Entities. |
| Graph | A set of Checkpoints connected through Transitions, where at least one of Checkpoints is an Initial Checkpoint. There is a path (through Transitions) between any two Checkpoints of the Graph. |
| External Graph | Graph that may involve more than one Supervised Entity. Its configuration is mode-dependent. |
| Cross-Cluster External Graph | A special kind of External Graph that spans over multiple Software Clusters for Clustered Software Architecture. Its configuration is mode-dependent (controlled by Host SWCL) and has dedicated configuration structure additionally. Note: External Graph within one Software Cluster can be modelled without the configuration structure dedicated for clustered software architecture. |
| External Transition | An External Transition is a transition between two Checkpoints, where the Checkpoints belong to different Supervised Entities. |
| Local Supervision Status | Status that represents the current result of alivesupervision of a single Supervised Entity. |
| Logical Supervision | Kind of online supervision of software that checks if the software (Supervised Entity or set of Supervised Entities) is executed in the sequence defined by the programmer (by the developed code). |
| Internal Graph | Graph that may not span over several Supervised Entity. Its configuration is mode-independent and can be disabled by disabling the corresponding Supervised Entity. |
| Internal Transition | An Internal Transition is a transition between two Checkpoints of a Supervised Entity. |
| Mode | A mode is a certain set of states of the various state machines that are running in the vehicle that are relevant to a particular entity, e.g. a SW-C, a BSW module, an application, a whole vehicle In its lifetime, an entity changes between a set of mutually exclusive modes. These changes are triggered by environmental data, e.g. signal reception, operation invocation. In the context of the Watchdog Manager a mode is defined by a set of configuration options. The set of Supervised Entities to be supervised may vary from mode to mode. |
| Supervised Entity | A software entity which is included in the supervision of the Watchdog Manager. Each Supervised Entity has exactly one identifier. A Supervised Entity denotes a collection of Checkpoints within an instance of Software Component Types or Basic Software Modules. There may be zero, one or more Supervised Entities in an instance of Software Component Types or Basic Software Modules. |
| Supervised Entity Identifier | An Identifier that identifies uniquely a Supervised Entity within an Application. |
| Supervision Counter | An independent data resource in context of a Supervised Entity which is updated by the Watchdog Manager during each Supervision Cycle and which is used by the Alive Supervision algorithm to perform the check against counted Alive Indications. |
| Supervision Cycle | The time base of Supervision Reference Cycle of Watchdog Manager, where the cyclic Alive Supervision is performed. And it’s also the interval for updating Global Supervision Status and execution of resulting Recovery Actions. This is done in every call of the Main Function of belonging Watchdog Manager and mode-dependent (may vary when swiching mode). |
| Supervision Reference Cycle | The amount of Supervision Cycles to be used as reference by the Alive Supervision to perform the check of counted Alive Indications (individually for each Supervised Entity) and mode-dependent. |
